Application filed April 2 1903. Serial No. 150,677- (No model.)

To (ZZZ whom it may concern.-

Be it known that I, LEWIS C. LANPHEAR', of

Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Exhaust-Ventilators forCars,- of which the following is a specification.

This invention has for its object to effect the proper ventilation ofrailway-cars withstruction, since the appliance is well adapted for useupon the greater numberof cars as now constructed.

Railway-cars both for steamand street railways are generally constructedwith what is known as a monitor-top -*that is to say, with anelevated.centrally-located roof and with windows below the roof, whichmay be opened to secure ventilation. with cars of this character is thatthe ventilation is improperly accomplishedthat is to say, warmer airescapes from some of the windows, while cold air is allowed to pass inthrough others, and thus create a draft which is injurious to thepassenger. Moreover, the opening of the windows allows the smoke,cinders, and dirt to enter the car and sift themselves over thepassengers.

According to my invention 1 place on the side of the monitor-top, alongthe line of the windows which are there located, a trunk or conduit,with which the interior of the car communicates through the windows justreferred to. The ends of this trunk are provided with doors, which maybe alternately opened and closed, according to the direction in whichthe car is moving, it being my purpose to have the door closed at thefront end and opened at the rear end, assuming that the front of the carbe that endwhich is traveling forward. In addition, the trunk isprovided at each end with an opening and with a wind deflector, shield,or wing. These are so connected to the doors that when a door at one endof the trunk is open the adjacent wing is swung outward. The efiect ofthis is, when the car is traveling rapidly, to in- The difficulty hingeddoor e.

duce a current of air through the aperture and through the end of thetrunk, so that by eduction the warm or vitiated air may be drawn awayfrom the top of the car.

On the accompanying drawings, Figure 1 represents in perspective viewthe top of a car equipped with the invention. Fig. 2 represents a sideelevation of the same. Fig. 3 represents the car in plan View, the partsbe ing shown in section. Fig. 4: represents an enlarged section on theline 4: 4 of Fig. 3. Fig. 5 is an enlarged horizontal section of one endof one of the trunks.

Referring to the drawings, a indicates the roof of the monitor-top, andb b represent the upright sides. These sides are provided with the usualglazed movable windows 0 e, which are to be ordinarily found instreet-cars and steam-railway cars. Outside of the sides b b are securedtwo trunks or conduits d d.

These are shown as quadrangular in transverse section, and they restupon the roof of the car on either side of the monitor-top. The outersides of the conduits or trunks are glazed at intervals, as shown at d,to permit the passage of light to the top of the car. At each end ofeach of the trunks there is a The doors of each trunk are connected bylinks 6 with a longitudinallymovable rod e so that when either one ofthe doors is open the other is closed. Each rod 6 is adapted to be movedlongitudinally by a lever gor' other suitable appliance projecting'downinto the car. The outer side of each of the trunks or conduitsis-provided.

near each of its ends with a swinging wing f. These wings are so hingedthat when they are moved outward they form vanes or deflectors fordeflecting the air through the apertures f, as shown by the arrows inFig. 3.

.Each of these wings is connected .witha rod 8 by a link f When the rode is moved to the left, as in Fig. 3, it moves the wing at the left endoutward to operative position and at the same time opens the door 6,which is adjacentthereto, also closing the other wing f and the otherdoor e. .Assuming now that the car be moving in the direction of thearrow in Figs. 1 or2 and the parts he in the position shown in Fig. 3,the air striking the vane or wing f will rush in through the apertureand out through the end of the trunk. This, I have found, will induce acurrent of air through the trunk and draw out the foul or vitiated airin the top of the car through the windows 0 c in the moniter-top. Thesewindows of course may be adjusted as ordinarily to suit the occasion orthe atmospheric conditions. When the car is to move in the oppositedirection, the rod 6 is movedvto the right by the lever g, so as toclose the door and wing which were previously opened and open thosewhich were previously closed.

By a ventilating appliance of this character it is apparent that it isimpossible for smoke or dirt to get into the car through the upperwindows and that the foul air is withdrawn without causing-drafts whichmight prove detrimental to the health of the passengers.

Although the window 0, immediately opposite the wing f, is shown asopened in Fig. 3, yet better results are obtained by keeping that windowclosed at all times, as it prevents air induced by the wingf fromrushing into the top of the car. 1 I

Of course it will be readily understood that the length of the conduitor trunk may be varied to suit particular requirements and that it maybelonger orshorter than the monitor-top.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, although without attempting to setforth all of the forms in which it may be made or all of the modes ofits use, I declare that what I claim is 1. An exhaust-ventilator forcars comprising a trunk or conduit extending longitudinally of the carand connected with the interior thereof, said trunk orcond nit beingclosed except at its rear end and having an aperture 1 at its side nearsaid end, said side being provided with a forwardly and outwardly pro-1vI jecting vane for deflecting air throughthe rear end of said conduit,and means for moving said vane in one direction to close the saidaperture or in the other direction to open said aperture and to deflectair thereinto substantially as described.

2. An exhaust-ventilator for cars comprising a trunk or conduitextending longitudinally of the car and connected with the interiorthereof, said conduit having in its side near its end an aperture, avane or deflector pivoted to said trunk and adapted to close saidaperture, and means for swinging said vane about its pivot to cause thedeflection of air into said trunk through said aperture.

3. An exhaust-ventilator for cars comprising a conduit or trunk arrangedlongitudinally of the car and communicating with the interior thereof,said conduit having apertures in its sides near its ends, doors at itsends and deflectors or wings at its sides near said apertures, each ofsaid doors and said wings being movable and substantially as described.

4. An exhaust-ventilator for cars comprising a conduit or trunk arrangedlongitudinally of the car and communicating with the interior thereof,said conduit or trunk having apertures at its sides near its ends andvanes adapted to be moved alternately to close or open said apertures,and means for simultaneously moving said vanes.

5. An exhaust-ventilator for cars comprising a conduit or trunk arrangedlongitudinally of the car and communicating with the interior of thecar, said conduit having doors at its ends and deflectors or wings atits sides near its ends, and means connecting said wings and said doorswhereby when the wing and door at one end are closed, the wing and doorat the opposite end are opened, and vice Versa.

6. An exhaust-ventilator for cars comprising a trunk or conduit arrangedlongitudinallyof the car and communicating with the interior thereof,apertures in the sides of said conduits near its ends, wings ordeflectors adapted to cover said apertures and also to be moved outwardfor the purpose of deflecting air inward through said apertures, doorsadapted to close the extremities of said trunk or conduit, and meansoperable from the interior of the car for opening and closing said doorsand said wings or deflectors.

In testimony whereof I have affixed my signature in presence of twowitnesses.
